USN-4192-1: ImageMagick vulnerabilities imagemagick vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 19.10 Ubuntu 19.04 Ubuntu 18.04 LTS Ubuntu 16.04 LTS Summary Several security issues were fixed in ImageMagick. Software Description imagemagick – Image manipulation programs and library Details It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program. Update instructions The problem can be corrected by updating your system to the following package versions: Ubuntu 19.10 imagemagick – 8:6.9.10.23+dfsg-2.1ubuntu3.1 imagemagick-6.q16 – 8:6.9.10.23+dfsg-2.1ubuntu3.1 libmagick++-6.q16-8 – 8:6.9.10.23+dfsg-2.1ubuntu3.1 libmagickcore-6.q16-6 – 8:6.9.10.23+dfsg-2.1ubuntu3.1 libmagickcore-6.q16-6-extra – 8:6.9.10.23+dfsg-2.1ubuntu3.1 Ubuntu 19.04 imagemagick – 8:6.9.10.14+dfsg-7ubuntu2.3 imagemagick-6.q16 – 8:6.9.10.14+dfsg-7ubuntu2.3 libmagick++-6.q16-8 – 8:6.9.10.14+dfsg-7ubuntu2.3 libmagickcore-6.q16-6 [ more… ]

USN-4191-2: QEMU vulnerabilities qemu vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 ESM Summary Several security issues were fixed in QEMU. Software Description qemu – Machine emulator and virtualizer Details USN-4191-2 fixed a vulnerability in QEMU. This update provides the corresponding update for Ubuntu 14.04 ESM. Original advisory details: It was discovered that the LSI SCSI adapter emulator implementation in QEMU did not properly validate executed scripts. A local attacker could use this to cause a denial of service. (CVE-2019-12068) Sergej Schumilo, Cornelius Aschermann and Simon Wörner discovered that the qxl paravirtual graphics driver implementation in QEMU contained a null pointer dereference. A local attacker in a guest could use this to cause a denial of service. (CVE-2019-12155) Riccardo Schirone discovered that the QEMU bridge helper did not properly validate network interface names.
